I have recently taken over as Yorkshire Natueralists' Union Orthoptera Recorder and am compiling up to date maps. In 2010, a large colony of Speckked Bush-crickets was found just west of Hull on the north bank of the River Humber. Another much smaller colony was found in 2011 at North Cave Wetlands LNR about 8 miles north west of the first site. I spent some time with a bat detector trying to locate any sites between but had no luck. There are a couple of recent records from the Dearne Valley in West Yorkshire suggesting that it might be breeding there.
I would like to work out where these colonies originated and am looking for recent sightings in Lincolnshire (especially North Lincs) and the Midlands north to South Yorkshire.
